Follow up

  • No init script deployment on alpine
  • Modify data_dir
  • Different configuration directory on alpine
  • Should use the new interface template go syntax, however it did not work on testing

Use alpine's init script:

[13:02] router1.place6:~# mv /etc/init.d/consul.apk-new /etc/init.d/consul
[13:03] router1.place6:~# cat /etc/conf.d/consul 
# Consul startup
consul_opts="agent -config-dir=/etc/consul" 
[13:04] router1.place6:~# 

Changing path to what we used on debian

[13:04] router1.place6:/etc/consul# vi /etc/conf.d/consul
[13:05] router1.place6:/etc/consul# cat /etc/conf.d/consul
# Consul startup
consul_opts="agent -config-dir=/etc/consul/conf.d"

Consul 1.6.2

Seem like old bind_addr now supports interfaces - much nicer!

However it does not work -- at the moment hard coded to the routers ipv6 address.
Also the conf.d change does not seem to work.

Seems to crash when running under supervise (probably permission error):
